Palamedes

It's a little device about the size of a home BP device. It has a strap that goes around your chest to measure your breathing. It also has headphones to give you audio feedback. It attempts to lower your breathing rate.

It's basically a stress reducing biofeedback device that they did some research on to allow them to claim that it reduces BP. There are several other such devices on the market. However, at around $300, it's reasonably priced compared to the alternatives. So, it's probably the best option if you want to try something like this.

The only thing I think is a little deceiving is the claim that it reduces blood pressure by 14/9 mmHg on average after 8 weeks of usage. The control group in these studies had a reduction of about 8/4. And, since most drugs list "placebo adjusted" values, a more fair reduction claim would be something like 6/5. So, I'd compare those results to about 1/2 a drug.

But, again, I think it's going to help out more with stress than BP. And, this isn't necessarily a bad thing. Furthermore, if stress is the primary source of your high BP, it will probably do more for you.
